2009 DODGE DURANGO Owners Manual

4. Tongue weight rating for the trailer hitch utilized
(This requirement may limit the ability to always
achieve the 10% to 15% range of tongue weight as a
percentage of total trailer weight.)
Towing Requirements — Tires

Do not attempt to tow a trailer while using a compact
spare tire.
Proper tire inflation pressures are essential to the safe
and satisfactory operation of your vehicle. For proper
tire inflation procedures, refer to “Tire Pressures”
under ”Tires–General Information” in Section 5.
Also, check the trailer tires for proper tire inflation
pressures before trailer usage.
Check for signs of tire wear or visible tire damage
before towing a trailer. For the proper inspection
procedure, refer to “Tread Wear Indicators” under
”Tires–General Information” in Section 5.
When replacing tires, refer to “Replacement Tires”
under “Tires–General Information” in Section 5. Re-
placing tires with a higher load carrying capacity will
not increase the vehicle’s GVWR and GAWR limits.
Towing Requirements — Trailer Brakes

Donotinterconnect the hydraulic brake system or
vacuum system of your vehicle with that of the trailer.
This could cause inadequate braking and possible
personal injury.
An electronically actuated trailer brake controller is
required when towing a trailer with electronically
actuated brakes. When towing a trailer equipped with
a hydraulic surge actuated brake system, an electronic
brake controller is not required.
Trailer brakes are recommended for trailers over
1,000 lbs (454 kg) and required for trailers in excess of
2,000 lbs (907 kg).
STARTING AND OPERATING 367

CAUTION!
If the trailer weighs more than 1,000 lbs (454 kg)
loaded, it should have its own brakes and they
should be of adequate capacity. Failure to do this
could lead to accelerated brake lining wear, higher
brake pedal effort, and longer stopping distances.
WARNING!
Do not connect trailer brakes to your vehicle’s hy-
draulic brake lines. It can overload your brake sys-
tem and cause it to fail. You might not have brakes
when you need them and could have an accident.
Towing any trailer will increase your stopping dis-
tance. When towing you should allow for additional
space between your vehicle and the vehicle in front
of you. Failure to do so could result in an accident.
Towing Requirements — Trailer Lights and Wiring
Whenever you pull a trailer, regardless of the trailer size,
stop lights and turn signals on the trailer are required for
motoring safety.
The Trailer Tow Package may include a 4 and 7-pin
wiring harness. Use a factory approved trailer harness
and connector.
NOTE:Do not cut or splice wiring into the vehicle’s
wiring harness.
368 STARTING AND OPERATING

The electrical connections are all complete to the vehicle
but you must mate the harness to a trailer connector.
Refer to the following illustrations:

Towing Tips
Before setting out on a trip, practice turning, stopping
and backing the trailer in an area away from heavy
traffic.
Towing Tips — Automatic Transmission
The DRIVE range can be selected when towing. How-
ever, if frequent shifting occurs while in this range, the
TOW/HAUL feature should be selected.
NOTE:Using the TOW/HAUL feature while operating
the vehicle under heavy operating conditions will im-
prove performance and extend transmission life by re-
ducing excessive shifting and heat build up. This action
will also provide better engine braking.
The automatic transmission fluid and filter should be
changed if you REGULARLY tow a trailer for more than
45 minutes of continuous operation. For transmission
fluid change intervals, refer to “Maintenance Schedule”
in Section 8.NOTE:Check the automatic transmission fluid level
before towing.
Towing Tips — Tow/Haul (If Equipped)
To reduce potential for automatic transmission overheat-
ing, turn the TOW/HAUL feature ON when driving in
hilly areas or shift the transmission to DRIVE position 2
on more severe grades.
Towing Tips — Electronic Speed Control (If
Equipped)

Do not use in hilly terrain or with heavy loads.
When using the speed control, if you experience speed
drops greater than 10 mph (16 km/h), disengage until
you can resume cruising speed.
Use speed control in flat terrain and with light loads to
maximize fuel efficiency.
370 STARTING AND OPERATING

Towing Tips — Cooling System
To reduce potential for engine and transmission over-
heating, take the following actions:
City Driving
When stopped for short periods of time, put transmission
in NEUTRAL and increase engine idle speed.
Highway Driving
Reduce speed.
Air Conditioning
Turn off temporarily.
refer to “Cooling System Operating” under “Mainte-
nance Procedures” in Section 7.
SNOWPLOW
Snow plows, winches, and other aftermarket equipment
shouldnotbe added to the front end of your vehicle. The
airbag crash sensors may be affected by the change in thefront end structure. The airbags could deploy unexpect-
edly or could fail to deploy during a collision.
WARNING!
Do not add a snow plow, winches, or any other
aftermarket equipment to the front of your vehicle.
This could adversely affect the functioning of the
airbag system and you could be injured.
RECREATIONAL TOWING (BEHIND
MOTORHOME, ETC.)
2WD Models
Recreational towing of 2WD models is not allowable.
Towing the vehicle with the transmission in NEUTRAL
can cause severe transmission damage. Removal of the
driveshaft for towing is not recommended since this
allows transmission fluid to leak out.
STARTING AND OPERATING 371

4WD Models
CAUTION!
Vehicles equipped with an NV 140 Transfer Case
(which has no NEUTRAL position) may NOT be
used for recreational towing.
WARNING!
You or others could be injured if you leave the
vehicle unattended with the transfer case in the
NEUTRAL position without first fully engaging the
parking brake. The transfer case NEUTRAL position
disengages both the front and rear driveshafts from
the powertrain and will allow the vehicle to move
even if the transmission is in PARK. The parking
brake should always be applied when the driver is
not in the vehicle.
CAUTION!
Internal damage to the transfer case will occur if a
front or rear wheel lift is used when recreational
towing.
NOTE:The NV 244 Generation II transfer case must be
shifted into NEUTRAL, and the transmission must be
shifted into PARK for recreational towing. The NEU-
TRAL selection button is located on the lower left-hand
corner of the 4WD Control Switch. Shifts into and out of
transfer case NEUTRAL can take place with the selector
switch in any mode position.
Shifting into NEUTRAL
Use the following procedure to prepare your vehicle for
recreational towing.
